RAILROAD-CAR' DUSTER AND VENTILATQR.

The Sehedule referred to in these Lettura Patent and making part of the sama I, JOHN PENN Gonny, of the city of New York. in

`t'hecounty of NewYork and State of New York,A

have invented a new and uscful'lmproved Railroad Duster, of which the following, is a 'speciii"atioi1.

The Nata-mand Ubjcct of my Invention. My invention relates to theV metailio curtains E, at-

-tached to the car, and extending down'outsidc of the wheels to near the ground, for the purpose ot'- retaining the dust beneath the can and providinfbr said our- .tains with slides or removable portions, S, so as to make the wheels and journal-boxes accessible, in con'ibination with reversible hood B, that can be turned either way, and catch or gather the wind and force it down the tubes or pipes beneath, said pipes heilig provided with ventilators, as will be more fully described hereafter. The objects ofthe hood and pipes or tubes are to gather theair as the car i'sfin mot-ion, and force it down beneath the car and allay the. dust, and prevent it from rising into the car. Description of theDmwiny.

Figure l representsa side elevation of a railway a', with my improvements attached, and

-General Description.

A representslany railway coach.'

B is a reversible hood or air-gatherer, plactd on partly over, so as to gather the air when the coach is moving in either direction.

C are' air-tubes or pipes, for conducting the air gathered by the hoods B down beneath the car.

E are the metallic curtains or `dustconiiners, for I the. car, and, by being pivoted, as shown, it will turnl confining the air and dust beneath the car, as hereafter described.

S are slides or doors, that can be slid back on t-he curtains E, to make openings for reaching the wheels and journal-boxes, and examinining and .re-

'paring the ruiming part of the car.

*V are openings in the air-tubes, with slides or c'overs, for-opening or closing them, to admit air into the car, as desired. .A tine wire-jauze, placed over the opening, servesto prevent any sand and cinders pass,n ing intothe car. The object oi' these openings is to rentilate the cars byforcing air through them.

Illhe metalliccurtains are suiiciently .rigid to hohl the pressure of air beneath them that is forced down through the tubes C, and, as the air is lheld confined beneath the car,V the dust and sand are kept from being raised, to a great extent, by the motion -of the car. The air heling compressed and confined beneath the ears all the while, the motion of' 'the car does not have` the same effect uponthedust and sami beneath the car as when the air is not compressed beneath the car. The principal object 0i' the curtain is toconfine the air that is forced beneath the cars, so that it will be compressed, and prevent the dust from rising.

Claim., fhat I claim as new, and desire to secure by Letters Patent, is-

The combination of the hood B, pipe C, ventilator V, and curtain E, when constructed and operatedsnb` stantially as herein set ibrth.
